This article discusses male androgenetic alopecia, describing its progression and pattern, and reports no new findings or clinical results.

This study observed that hair follicle mesenchyme in mice exhibits significant plasticity during the hair cycle, with cell migration and changes in papilla size impacting hair production.

This review highlights advancements in applying single-cell sequencing to cattle, sheep, and goats, noting its potential to elucidate cellular diversity and improve traits affecting livestock health and productivity, despite challenges in cell population annotation and spatial resolution in these species.

This study found that in domestic cats, black hair contained significantly higher cortisol concentrations than white hair, whereas ginger hair showed no significant difference compared to white hair. Additionally, a positive correlation was reported between hair cortisol levels and behavioral issues mentioned by cat owners.

This review discusses the use of hair analysis for examining stress and reproduction hormone levels in wildlife and highlights the need for more comprehensive physiological validations across species.

This study identified multiple loss of function variants in the HR gene linked to the unique hair coat phenotype in lykoi cats, also known as werewolf cats.

This study demonstrates that T-cell responses in extensive alopecia areata scalp may be aberrantly regulated, with reduced cytokine production but activated phenotype, providing insight into the disease's immune mechanisms.

This study generated a gene-edited cashmere goat with improved cashmere yield and fiber length by integrating VEGF at the FGF5 site, offering insights into hair growth mechanisms.

This review summarizes 25 small molecule drugs with in vitro and in vivo data for COVID-19 treatment, highlighting their structural diversity and potential to guide future antiviral discovery.

This study reported that 5% minoxidil nanoparticles enhanced hair growth more effectively in mice than a commercial minoxidil solution, with significantly higher drug accumulation in the upper hair follicles.

This study proposes that the ability of humans to grow long scalp hair is linked to the evolutionary adjustment of molecular checkpoints that regulate the hair growth cycle, potentially influenced by its roles in communicating age, maturity, and social signals.

This study found that prostaglandin receptors are widely expressed in hair follicles, suggesting a complex network of prostanoid pathways involved in hair growth control.

This research observed that 5α-reductase inhibitors showed significant tic-suppressing effects in Tourette's syndrome, suggesting a key role for this enzyme in the disorder's pathogenesis.

In this study, researchers found that high hair cortisol levels, indicating stress in cows, were associated with certain shelter and cow-level conditions such as unclean environments and physical injuries.

This study found that Physcion from Polygonum multiflorum may be an effective natural 5α-reductase inhibitor for treating androgenic alopecia by enhancing hair growth and improving follicle morphology in laboratory settings.

This study found that progesterone levels were higher and increased significantly throughout pregnancy, contrasting with stable levels in non-pregnant women.

This study found that older steers had higher hair cortisol concentrations compared to younger steers, suggesting age affects chronic stress biomarkers in beef cattle.

In this study, cyclosporin was found to prolong the hair-existing phase in nude mice, while corticosteroids inhibited its effect and suppressed hair regrowth.

In this study, researchers observed that chronic stress affected wild-derived house mice differently by sex, with females showing less weight gain and distinct behavioral changes, while males exhibited higher hair corticosterone levels, suggesting divergent coping strategies and implications for sex-specific stress assessment protocols.

This study found that the MD-3 antibody significantly improved the survival of hair follicle allografts in nonhuman primates by reducing T-cell infiltration.

This study reported that alopecia in giant pandas may be linked to abnormal expression of several hair-related genes and pathways, providing insight for potential prevention and treatment strategies.

This study found that microneedle delivery of Polygonum multiflorum extract led to earlier pigmentation and hair regrowth in mice with androgenetic alopecia.

This review discusses sex differences in immune responses and highlights mechanisms involving sex hormones, X-linked genes, and X-Chromosome Inactivation, but reports no new clinical findings.

This study found that while the KRTAP gene family is unique to mammals, humans have a similar number of these hair gene types as other primates despite having less body hair.

This review discusses the potential of microneedles to enhance transdermal drug delivery by expanding the range of deliverable drugs, highlighting fabrication methods, material choices, and applications, but notes existing challenges with sustained delivery, cost-effectiveness, and large-scale production.

This article reviews the use of bimatoprost for eyelash hypotrichosis and reports its effectiveness in promoting eyelash growth but highlights uncertain efficacy in cases of eyelash alopecia areata.

This paper discusses the role of Runx1 in epithelial biology and pathology, highlighting its dual function as a tumor promoter and suppressor in different contexts, and reports no new experimental findings.

This review discusses the production, role, and measurement of dihydrotestosterone (DHT) in various disorders of sexual development but does not report new clinical results.
